Write a function that takes in an array of integers and returns a boolean representing whether the array is monotonic. | |
An array is said to be monotonic if its elements, left to right , are entirely non-increasing or entirely non-decreasing. | |
Non-increasing elements aren't neccessarily exclusively decreasing; they simply don't increase. Similarly, non-decreasing elements aren't exclusively increasing; they simply don't decrease. | |
Note that empty arrays and arrays of one element are monotonic. | |
